This dataset is the focus of our blog post, How to Remove Shape from a Complex Surface. In the post we show how to use the tools in OmniSurf3D to tame a difficult surface and accurately measure features despite the complicated, underlying surface.

Measured via GelSight Mobile.
Data source: Asist. Prof. Alp Eren Şahin and Prof. Dr. Tamer Sınmazçelik from the Mechanical Engineering Department of Kocaeli University in Kocaeli, Turkey.
